The working principle is as follows:
when the device is installed:
firstly, the submersible pump 1 is started, water at the bottom in the vertical shaft 10 is led into the submersible pump water outlet pipe 3 from the submersible pump water inlet 2 of the submersible pump 1, flows through the heat dissipation water inlet pipe 6 and the water inlet hose 18 of the device, enters the heat dissipation water pipe 32, returns to the water inlet hole 24 of the dam pier 28 through the U shape, enters the water outlet pipe 35, flows out from the bottom of the bottom plate 27 to the opened water outlet valve 16 (manual) position, and when water flows out, the submersible pump 1 is closed, and the check valve 4 prevents the water from flowing back.
Water flows through the submersible pump 1, the submersible pump water outlet pipe 3, the heat dissipation water inlet pipe 6 and the water inlet hose 18 to enter the heat dissipation water pipe 32, returns to the water outlet hose 23 through U-shaped turning back, and enters the water outlet pipe 35 to form a starting water path.
At this time, because the water level (rubber dam water level 17) in the shaft 10 is always higher than the water level at the position of the water outlet valve 16, water enters from the bottom of the water inlet pipe 5 to form inverted siphon, enters the heat dissipation water pipe 32 at the heat dissipation water inlet pipe 6 and the water inlet hose 18, returns to the water outlet hose 23 through U-shaped turning back, and enters the water outlet pipe 35.
The water flows outwards from the water outlet valve 16 opened at the bottom of the bottom plate 27, and the higher-temperature water sucked up from the bottom of the shaft 10 in the heat dissipation water pipe 32 plays a role in melting ice and preventing freezing at the colder water surface in the process.
Water flows into the heat dissipation water pipe 32 through the water inlet pipe 5, the heat dissipation water inlet pipe 6 and the water inlet hose 18, returns to the water outlet hose 23 through U-shaped turning back, enters the water outlet pipe 35, and flows to the downstream of the rubber dam from the water outlet pipe 35 buried in the bottom plate 27 and the abrupt slope section 31 of the stilling pool to form an ice water melting inverted siphon water path.
When the device is not used, the water outlet valve 16 is closed, and when the device is used next time, the primary submersible pump 1 is started again, then the submersible pump 1 is closed, and then the inverted siphon work is started.
The device can be arranged in two dam piers 28 at two sides of a rubber dam bag 26 respectively, two U-shaped heat dissipation water pipes 32 which are horizontally arranged in parallel respectively occupy half width of the water surface of the dam front water retaining part 29, and respectively absorb water with higher bottom temperature in the vertical shaft 10 in the two dam piers 28 to the water surface (ice surface) of the dam front water retaining part 29 with lower temperature.
When the submersible pump 1 is started, part of water flows out from the water inlet below the water inlet pipe 5, and the water supply of the heat dissipation water pipe 32 above the heat dissipation water inlet pipe 6 is not influenced.
When the rubber dam pier 28 is cast with concrete, a vertical shaft 10, a water inlet hole 24, a cable well 13 and a connecting cable trench 15 are reserved at the front edge of the rubber dam pier, and the cable well 13 is communicated with a bottom cable trench 33 reserved in a bottom plate 27. The position of a water outlet pipe 35 is reserved at the bottom of the bottom plate 27 and the stilling pool steep slope section 31.
